Net Reclassification Improvement (NRI) and Clinical NRI for Various Endpoints for Baseline Troponin Assessed by Contemporary-Sensitivity, High-Sensitivity and Super-Sensitivity Assays in Addition to the Standard Framingham Risk Score.

NRI = net reclassification improvement, clinical NRI = NRI for individuals with an intermediate 10-year risk (5–20%) according to the Framingham Risk Score, MACE = major adverse cardiac events, CVD = cardiovascular disease, MI = myocardial infarction, HF = heart failure, cs-cTnI = troponin I measured by contemporary-sensitivity assay, hs-cTnI = troponin I measured by high-sensitivity assay, ss-cTnI = troponin I measured by super-sensitivity assay, ns = not significant.
